Two circles of radii 5 cm and 3 cm intersect at two points and the distance between their centres is 4 cm. Find the length of the common chord.
Question
Solution 1
To solve this problem, we can use the formula for the length of a common chord between two intersecting circles. The formula is:
Length of common chord = 2 * sqrt[(r1^2 - d^2) + (r2^2 - d^2)]
where r1 and r2 are the radii of the two circles and d is the distance between their centres.
